TROLLEYeHEAID.

Speeicaton oi' Letters Patent.

Application filed February 26, 1914. Serial No. 821,256.

To all whom it may concern: Be it known that I, CLYDE W. immune, a

` citizen ofthe United States, residing at Vancouver, in the Province ofBritish Columbia, Canada, have invented certain new and usefulimprovements in Trolley-Heads, of which the followingis a specification.

This invention relates to a trolley head for the pole of an electric carand is designed to retain the trolley wheel against lateraldisplacement. from the wire freni which the current is derived.

lhe invention is particularly described in the following,-specification, reference being made to the drawings hy which it isaeconr panied, in which:

Figure lis a side elevation of the trolley head. llig. 2, a front viewof the saine, and Fig. 3, an end View showing the manner of maintainingthe guide wires in position in `relation to the trolley or current wire.

ln these drawings 3 represents the trolley wire and 8 the trolley pole.

Secured on the upper end of the trolley pole 8 is a light head meinherel which carries the `trolley wheel or roller 2 through which current isconducted to the car from the trolley wire 3. rlChis 'wheel 2 instead ofbeing,` deeply grooved, as is usual, to retain it on the wire 3, is ofsubstantial width, say from four to six inches, and is tapered smallerfrom each side toward the middle, where a slight circumferential groove7 is formed in it for the wire 3. This wheel 2 is mounted to rotate on aspindle secured in the head and cylindrical side rollers G are similarlymounted on each side, the artis ot' rotation of the side rollers being,lat right angles to that of the trolley wheel 2. "he attachment of thetrolley head lto the trolley pole 8 is at such an anule that the siderollers will he substantially vertical at the normal angle of backwardrake of the trolley pole. rlhis trolley head designed to be used withatrolley wire 3 haring;l a guide wire (l on each side and below it thatwill prevent lateral movement of the trolley wheel on the wire 3. rlhewires G are maintained a lined distance apart and from the trolley wire3 hy `any suitable means. Fig. 3 shows a convenient ineens for sosupport- "ing the trolley and guide wires by means of a yoke l0 to whichthe Guy wires ll are connected which carry the trolley wire. By

this means the trolley wheel is positively retained against `lat eraldisplacement on the trolley wire and the retaining,1 means has notendency to free itself from the retaining engagement, as is the casewith the deep side flanges of the customary trolley wheel.

The device is simple and comparatively inexpensive as the guide wires Gare not conducting wires, the current being` carried entirely by thetrolley wire 3. y

llaving new particularly described my invention, l hereby declare thatwhat l claim as new and desire lto be protected in by Letters Patent,is:

l. A trolley head, comprising the combi` nation with a trolley 'wirehaving; a guide wire helow it ou. each side, of a trolley head securedto the trolley pole at an angle that will sustain that portion of thehead within the side wires substantially Vertical, a trolley wheelrotatably mounted in the upper end of the head and a side roller on eachside of the head, the axis of each side roller at `right angles to thatof the trolley wheel.

A trolley head, comprising the combi` naaien. with a trolley wire havinga guide wire lielow it on each side, of a. trolley head secured to thetrolley pole at an angle that will sustain that portion of the headwithin the side wires substantially vertical, a trolley wheel rotatablymounted in the upper end of the head. said wheel harina acircuinferential groove at its mid-width and conically enlargedsligig'htly toward each side, and a cylindrical roller mounted on eachside of the head on an axis that is at right angles to that of thetrolley wheel.

3. rl trolley head, ceinprising` the combination with a trolley wirehaving a guide wire below it on each side, of a trolley head secured tothe trolley pole at an angle that will sustain that portion of the headwithin the si de wires substantially vertical, a trolley wheel rotatablymounted in tue upper end of the head, said wheel having' a width greaterthan its diameter' and cireiunferential groove in its inidwidth and aside roller rotatably mounted on each side of the head. ln testimonywhereof l allix my signature in presence of two witnesses.
